Søren Mexico:

Forgot to tell you, when I get kits from Martin he nearly always provide one voltage step higher on the caps, surfing the net and learning I have seen this same recommondation on more websites, and dont forget your trimmers.

Yes, this is very good advice. I always do this when recapping. This does seem to be a universal method.

I published the standard values and recommend oversizing. The reason I haven't posted the oversized caps is because I do not want people to double oversize their order and end up with caps that won't fit.

By the way, I have also recorded the caps in the BM4500, will post them later tonight. Will also include trimmers.

Søren Mexico:

Hi Evan looking forward to see your work advancing;

Did you take the values direct in the BG CD, or from the manual list, if from the list, be careful, its not always the same as in the actual BG.

The changeout of the caps in this machine will probably take a while, the 4500 is second in line to my 3000-2!

Yes, I know better than to trust the service manuals I recorded these values directly from the capacitors.

Good evening all,

Sitting down with my 4500 pieces tonight to itemize them for a capacitor change. They started acting up a while ago and could use some attention in the electrical areas - something I neglected during the original restoration work.

Thanks Nidul!! Glad these old threads are still enjoyable.

I have organized all of my projects with direct links in my profile, for everyone.

As far as the material you are looking for, I'm sure it is available, I just don't know of any. However, if you re-read the thread carefully you will notice a few other members have posted links to companies who produce such products.

If you enjoy working with your hands, I would suggest using paint in your projects as well - there is a great sense of satisfaction that comes with hard work. If your pieces are in mint condition and you want a process that is reversible, proceed with your original plan.

And please, post your progress! All of us here on BeoWorld love these threads. Good luck on your new project!!

Hi Evan,

Congratulations on another great thread, I keep stumbling across these great reads, and get inspired. Thank you for creating these threads. I look forward to stumbling across another one. I a thinking of doing something similar to a Beocenter 8000 but I was going to use the stick-on plastic sheets that can be cut and stuck on to the surfaces. When I tackle this project I also hope to create a picture write-up just like this. Your work is inspirational. I do have one question and that is can I get this sticky plastic sheets in Gold, as I really like the idea of Black and Gold as a classy and unique colour scheme which is rarely seen on B&O equipment. Hope to hear fro you soon Buddy.

IkeA:

Evan, I LOVE what you've done to your Hot-Rod Beosound 4500 "Custom".
The minute attention to details makes your system stand out! It is this attention to deatil that separates a "Show Winner" from the other Hot-rod wannabees!

Hello IkeA, thank you for your wonderful comment!!! I am also delighted that my thread has been able to assist you

Come to think of it, I never did look at the bottom of my BeoMaster. It was in 100% perfect working order so I didn't bother. At first, your pictures did alarm me but Mika's comments calmed me down!

I do have plans to resume this thread and do a technical restoration this summer. I want my amp in top spec because I have this crazy idea of adding more speakers...
